It is understood from the inscription of the building that it was built for Emir Sadreddin Ömer bin Celaleddin Muhammed in the 580's (A.D. 1184). All the decorations of the cupola, which is very plain inside, are located on the north door and around the window on the west façade. Herbal ornaments are also seen in the cupola, which is dominated by geometric ornaments. On the upper floor, which is paved with stone, there is a stone sarcophagus placed during the last repair.
The body of the cupola, which is made of cut stone, has a square plan up to half, and the upper part has a conical roof. The door, located on the left side of the northern façade of the cupola, is accessed by seven steps.
